November 28, 2016

Puppet has appointed Mark Iserloth as Chief Financial Officer (CFO) and Marianne Calder as Managing Director and VP of Europe, Middle-East and Africa (EMEA). Puppet also promoted Nick Smyth to VP of Engineering.


As CFO, Iserloth will oversee finance and business operations, and will be part of the executive management team that will lead Puppet as it continues its rapid growth and international expansion.

“Mark is a proven leader and his background aligns perfectly to Puppet’s culture and business at this pivotal part of our growth journey,” said Sanjay Mirchandani, Puppet CEO. “With extensive experience in software, services, and international operations he has the drive and capabilities we need as Puppet embarks on our next phase of growth.”

With 16 years of experience as a CFO, Iserloth has led finance and human resources teams through the acquisitions of several companies, led an IPO process, and overseen all regulatory filings for a publicly traded company. Prior to joining Puppet, Iserloth was CFO at STATS, LLC., where he was responsible for finance, accounting, human resources and additional administrative functions. Prior to joining STATS he held CFO positions at Mattersight, Trustwave and Initiate Systems. Iserloth has extensive experience at a range of organizations, including hyper-growth private companies and large global, publicly traded companies. Iserloth holds an MBA from the J.L. Kellogg Graduate School of Management at Northwestern University and a B.S. in Electrical Engineering from Northwestern University.

“I’m incredibly excited to join Puppet,” said Iserloth. “As the market leader in a large untapped market with innovative technology and a great culture, Puppet has all the characteristics I look for in a great company. I’m looking forward to contributing and being a part of its success.”

New VP of EMEA

As Managing Director and VP of EMEA, Calder will lead Puppet’s customer operations, including sales, marketing, and customer success throughout EMEA to help fuel Puppet’s aggressive expansion in the region.

“Our vision is to enable every organization around the world to leverage software automation as a means of driving new innovation in the marketplace, quickly and confidently,” said Sanjay Mirchandani, CEO of Puppet. “We already have a large customer presence in the region — including three of the five largest banks in Europe, the largest telecoms, and some of the most recognizable brands — but we’re just getting started. By adding Marianne to our talented executive team, we’re able to aggressively devote more resources towards scaling our international presence so we can realize our vision globally.”

Calder most recently served as managing director of collaboration sales at Cisco, where she led the sales and architecture team to growth, and set the strategic direction for the $1 billion collaboration business in EMEAR. During her 21-year career at Cisco, Calder also drove the transformation of Cisco’s EMEAR inside sales organization and was integral to the creation and development of the global accounts program, which at the time represented more than 30 percent of Cisco’s business.

“I joined Puppet for the huge opportunity in front of us. For companies to thrive in the next decade, they need to be able to transform their business to meet the demands of today’s software-driven world,” said Calder. “Puppet is the cornerstone for making this transformation happen. I’m excited for the opportunity to lead Puppet’s global expansion and bring the transformative power of Puppet to even more organizations by building a highly collaborative team and a robust partner ecosystem.”

VP of Engineering

Nick Smyth, new VP of Engineering, is a 20+ year technology veteran, having led engineering and technical teams at Nortel, IBM, and Puppet. In his tenure at Puppet, Smyth has proven his leadership and has delivered at the highest levels. He brings strong engineering disciplines alongside a strong customer focus, and has been instrumental increasing product velocity at Puppet. Smyth will continue to work from Puppet’s Belfast office.
